.TO ALL WHOM IT MAY CONGERN:

Be it known' that I, WILLIAM PALMER, of theicity, county, and State of New Yotk,'haye invented, made, and applied to use a certain new and useful improvement for holding Blind-Slate; and I do hereby declare the foilowing tube a full, clear, andexact description of the said invention, reference being had to the accompanying drawings, making part of this specication, wherein- Figure l'is an elevation.

Figure 2 is a longitudinal section.

Similar letters of reference indicate the same parts.

Mechanical devices have heretofore been made for holding blind-slats; my invention does not relate to either of these devices,as they are well known. v

My'Y said invention consists of a single half-elliptic spring 'with the ends turned in, yin order to hold the same, or other mechanical device may be used for the purpose of ,holding the spring in place. In the drawing, A represents the stile, B the blind-slats, C the stayrod,nnnited or connected in the usual manner to the blindslats; D the spring. The spring D is placed on the inside of thepstile, between the stile and thc ends of the blind-slats, and is always in contact with one or more -of the blind-slats, and, by the friction of the spring D, the blind slats are-always held in any desirable position.

Having described my invention, I will now state what I claim, and desire to secure by Letters Patent I claim the adjustable half-elliptic spr-ing D, as arranged and constructed, and 4for the purposes as set forth.

WILLIAM PALMER.
